摘要
采用聚乙烯吡咯烷酮(PVP)作为保护剂,硼氢化钠(NaBH4)作为还原剂制备了纳米银。实验结果表明聚乙烯吡咯烷酮与硝酸银(AgNO3)的比例、不同分散介质以及不同放置时间在合成中对纳米银的粒径有一定的影响,并且对纳米银溶胶的稳定性也有很大影响。
Using polyethylene pyrrolidone(PVP) as protecting agent,borohydride sodium(NaBH4) as reducing agent,nano-silver was prepared,then characterization of nano-silver was carried out.The experimental results indicate that ratio of PVP and silver nitrate(AgNO3) proportion,different dispersion media and different storage time have certain effect on particle size of nano-silver and stability of nano-silver sol.
